We’re excited to share our study looking at molecular classification and survival of 4,400 #gliomas @NeuroOnc
A huge team effort over the years @MGBNeurosurgery @BWHNeurosurgery @DanaFarber, here’s what we found. 1/10

Not before your pathologist does! Important opportunity for pathologists and other diagnosticians to communicate their results directly to patients and explain results. Patients need to advocate for this as it’s not currently supported by insurance. #pathology

MALIGNANT PERIPHERAL NERVE SHEATH TUMOUR. Underlying NF1. IHC: SOX10, H3k27me3. NB: spindle-epithelioid cells with pale amphophilic cytoplasm; ovoid-round nuclei with moderate pleomorphism and conspicuous mitotic activity; variable collagenous-myxoid stroma.

Rare example of chondroma arising in the dura (falx). Histo shows characteristic mature hyaline cartilage with increased cellularity and mild nuclear atypia.

Not all EMA tumors in the dura are meningiomas. Do you recognize this one?
(EMA immunostain is shown for reference.)

Additional IHC (CD99 /des /SSTR2-) was highly characteristic of Intracranial Mesenchymal Tumor, FET::CREB fusion positive. EWSR1 FISH showed rearrangement. This particular case has a solid growth pattern with no myxoid stroma.

Can you diagnose in one cell?

A good clue is the presence of lymphoglandular bodies in the background. Smear prep is probably the best way to diagnose CNS lymphoma at frozen section.
Here is the accompanying H&E permanent section and CD20.

Nice example of a clear cell meningioma with the characteristic "blocky" collagen and absence of SMARCE1 expression.

An infant presented w/an intra-axial frontal lobe lesion. A craniotomy for total resection was performed, and H&E of the brain lesion showed the following. What is your differential diagnosis? What stains would you get? #BWHPathCotW #BWHNeuroPathWinter
